FIELD

This disclosure relates to automated devices and more particularly automated devices for use in distribution of biologic drugs.

BACKGROUND

Automated devices such as vending machines have been used for dry goods, refrigerated foods and/or frozen foods for a long time. The vending machines are placed in locations convenient to the consumer. When the consumer desires the product, he or she physically deposits cash or a credit card into the machine, makes a selection and receives the product.

More recently, automated devices have been used for conveying regulated pharmaceuticals. In acquiring regulated pharmaceuticals, a consumer in addition to providing payment must also provide documentation in some manner that they are eligible and permitted to receive the product. In this case also, the consumer physically interacts with the automated device to provide payment and permission for obtaining the product. These pharmaceuticals generally include dry or liquid pharmaceuticals and are regulated in order to prevent fraud and/or abuse.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The present description relates to an automated device or vending machine for live biological drugs. The biologic drugs include living cells that are maintained in a frozen state in the vending machines. The vending machines are generally placed in a point-of-care site, for example, a clinic, a hospital or other healthcare setting. The vending machine may also include a connection to a remote location generally through a secure internet connection. The connection can be used to transmit patient information such as medical records and details regarding financial payment. The remote location can be anywhere in the world and can be staffed by people that can verify the patient records and collect payment for the biologic drugs or obtain sufficient information regarding commitment for payment. Once the patient is approved for receiving the biologic drug, the patient, doctor or other healthcare worker can interact with the machine directly or through the use of a computer and start the processing cycle. Alternatively, the automated device may receive a code directly from the remote site through an internet connection to start the processing of a sample of the biologic drug.

The processing cycle can include, for example, retrieving a dose of the living cell drug, thawing, washing, incubating and formulating the sample for administration to the patient. The processing cycle can have a variable time duration and can be as little as several minutes or as long as a day. In exemplary embodiments, the processing cycle may take several hours. The actual events and components involved in the processing cycle can vary and depend on the specific biologic drug dispensed and formulated for administration to a patient. Upon completion of the processing cycle by the vending machine, the biologic drug can be retrieved by a person such as a health care worker and administered to the patient. Health care workers can include a doctor, nurse, technician and the like. A patient or a layperson trained in handling the biologic drug may also retrieve the biologic drug from the automated device.

Storage and processing of the biologic drug in an automated device as described herein advantageously alleviates the patient's need to travel to a site where the biologic drug is manufactured. In other words, the method employed herein for storing and processing the biologic drug enables the drug to be manufactured anywhere in the world and be used by a patient at a point of care site anywhere in the world. In addition, since the processing of the sample is performed in an automated device there is less chance of the sample being mishandled by a worker.

The present description also includes a novel business method. This method includes preparing a frozen biologic drug in a manufacturing facility and distributing the frozen drug to point-of-care sites. The frozen biologic drug is stored in an automated device capable of maintaining the drug in a frozen state at a point of care site until needed by a patient. When a doctor prescribes the use of the biologic drug to a patient, the patient's medical information and financial payment information is transmitted over a secure link to a remote location for authorization. Upon authorization, the automated device can be activated to initiate a processing cycle to prepare the drug for administration. The doctor or other authorized healthcare worker can obtain the drug after completion of the processing cycle and administer it to the patient. Alternatively, the patient may retrieve the formulated drug from the dispensing chamber and self-administer the drug.

The biologic drugs placed in the automated devices include living cells that have been manipulated in a number of ways. These manipulations include cells that have been proliferated, differentiated, activated and the like. In some embodiments, these living cells are immune cells and other embodiments, the living cells are activated T-cells. These immune cells may have been activated as described, for example, in U.S. Pat. Nos. 7,435,592, 7,678,572 and 7,402,431 incorporated herein by reference. Living cells as described herein include cells that can be frozen, thawed and when placed in appropriate media can be viable living cells that carry out cellular functions. The cellular functions can include secretion of molecules, proliferation, differentiation and the like. The cellular functions can be carried out in vitro and/or in vivo. For purposes of this application the term cell(s) can include prokaryotic and eukaryotic cells. In some preferred embodiments, the cells are eukaryotic cells. The biologic drug generally includes human cells but cells from other animals can be amenable to frozen living cell storage.

The living cells after being manipulated in the desired manner for obtaining a biologic drug can be prepared for long-term storage by freezing in the appropriate manner. The long-term storage can include suspension of the cells in media suitable for maintaining the viability of the cells during freezing and upon thawing.

In one exemplary embodiment, the method of distributing a biologic drug is as shown in the flow chart of FIG. 1. In this method, the living cell biologic drug is prepared in a manufacturing facility meeting the appropriate standards (step 10). After manufacturing of a batch of the biologic drug, the biologic drug is divided into individual doses and placed into vials or other suitable containers (step 20). The containers with the individual doses are frozen for long-term storage (step 30), preferably at about 70° C. Some desired number of doses can be shipped to point-of-care facilities around the world (step 40). The shipping method used can maintain the cells at the desired temperature, i.e. about 70° C. The point-of-care facility, upon receiving the shipment of frozen biologic drug samples, stocks an automated device (a vending machine) already present at the site (step 50). The biologic drug is stored in the storage chamber of the vending machine at the desired temperature until needed by a patient.

In step 60, a patient, examined by a doctor, is identified to benefit from the biologic drug in the vending machine. Patient information is transmitted (step 70) to a remote location. The patient information can include, for example, patient's medical records, patient's financial, payment and/or insurance information. Other information regarding the patient deemed necessary or useful may also be transmitted to the remote location. The patient information may be transmitted through a secure internet connection within the automated device or connected to the automated device. Alternatively, the patient information may be transmitted by a worker in the point of care facility through any other computing system with an internet connection or using other methods of information transfer, preferably in a secure manner.

In step 80, a person at a remote location receives the patient information and determines if the patient will be authorized to receive a dose of the biologic drug in the vending machine. Authorization determination can be made based on the patient medical condition, payment from the patient, and/or commitment of payment from the patient. Once the patient is approved for receiving the biologic drug, the point-of-care facility is notified and given permission to start the processing cycle of the frozen biologic drug (step 90). The point-of-care facility, for example, may be given a code that must be entered into the vending machine for the processing cycle to begin. Upon entering the code, one dose of the biologic drug is moved from the storage chamber to the processing compartment(s) (step 90). After the processing, the formulated drug is dispensed from the vending machine (step 100), removed and administered to the patient (step 110).

In an exemplary embodiment as shown in FIG. 2, vending machine (200) includes storage chamber 210 holding multiple doses of vials 220 containing the frozen biologic drug described herein. Storage chamber 210 is within cooling unit 230. Cooling unit 230 can include a variety of cooling processes, and preferably maintains the biologic drug in vials 220 at the desired temperature, for example, about −70° C. Vending machine 200 also includes power cord 214 that connects to a power source. Vending machine 200 includes system 300 capable of having a secure internet connection. System 300 can be, for example, a computing system with a secure internet connection. The internet connection is capable of communicating with computer 340 at a remote location. The remote location can be, for example, in the next room, across the country or across the world. System 300 is capable of accessing patient information about a specific patient and transmitting the information to computer 340 at remote location. System 300 may be configured to access patient information in a variety of ways including from removable data storage components such as a flash drive or zip drive or from accessing a network or a computer at the point-of-care site that has the patient information. System 300 may include, for example, keypad 310, display screen 320 and start button 330. A worker at the remote location can review the patient information and if satisfactory, can approve the patient for receiving a dose of biologic drug in vial 220. Once the patient is approved, computer 340 at a remote location can transmit authorization. Authorization can be verbal to a health worker from a worker at the remote location. Verbal authorization can simply instruct the health worker to press start button 330 to initiate the processing cycle. Alternatively, the health worker may be given a code to enter into keypad 310 to initiate the processing cycle. Display screen 320 may display the status of vending machine 200, for example, it may display “processing sample”, “washing sample”, etc. Alternatively, authorization can be by means of transmittal of a processing cycle initiation code directly to system 300 of vending machine 200 from computer 340.

In vending machine 200, upon receiving a start or initiation signal, vial 220 is moved to thawing chamber 240 in processing compartment 236. In thawing chamber 240, vial 220 is thawed to form thawed sample 220 a. Thawing chamber 240 has the appropriate components and/or materials necessary for thawing a biological sample. Chambers 250, 260, and 270 can be washing, incubating and formulating chambers, respectively. Chambers 250, 260 and 270 also have the appropriate components and/or materials necessary for carrying out their respective processing steps. The samples in vials 220 b, 220 c and 220 d are washed sample, incubated sample and formulated sample, respectively. Once the sample is formulated, it is moved to dispensing chamber 280. Vial 220 e in dispensing chamber 280 can be removed and is ready for administration to the patient. Generally, the formulated sample is administered to the patient immediately or as quickly as possible. Preferably, the sample is administered to the patient within 4 hours of formulation. The biologic activity of the sample can decrease with time after the formulation of the sample.

Chambers 240, 250, 260 and 270 can be any type of chambers, i.e. thawing, washing, mixing, and can be specific to the specific requirements of the biologic drug stored in vending machine 200. Embodiments are also contemplated wherein vending machine 200 includes only one chamber for all of the processing and the different steps in the processing are conducted while the sample is in the one chamber.

A variety of biologic drugs can be manufactured, stored and dispensed using the devices and methods described herein. In an exemplary embodiment, the manufacturing of a biologic drug at a remote facility includes obtaining T-cells from a healthy donor and differentiating these T-cells ex vivo. The ex vivo preparation of cells can include engagement of the CD3 and CD28 cell surface proteins through cross-linking, for example, by anti-CD3 and anti-CD28 antibodies as described in, for example, U.S. Pat. No. 7,435,592. The ex vivo prepared cells can be frozen prior to transporting to a point of care facility.

At the point of care facility, the frozen ex vivo prepared T-cells can be stored in an automated device and processed or formulated for administration upon receipt of authorization or approval of a patient for the biologic drug. The processing includes thawing the biologic drug and reactivating just prior to administration to a patient. The reactivation of the cells can be as described in U.S. Pat. No. 7,402,431. Briefly, the frozen cells can be thawed and reactivated by engaging cell surface proteins CD3 and CD28. The reactivation can include cross-linking the CD3 and CD28 proteins with, for example, anti-CD3 and anti-CD28 monoclonal antibodies. In some embodiments, the anti-CD3 and anti-CD28 monoclonal antibodies are attached to biodegradable particles. These reactivated allogeneic T-cells produce interferon-gamma and express high density CD40L on the cell surface.

The biologic drug stored and processed in automated devices described herein exhibit a substantial amount of biological activity. The amount of biological activity exhibited can vary and depend on the length of storage, the conditions of transport and storage, the specific biologic activity and the nature of the living cells. Preferably, the biologic drugs described herein, upon formulation, exhibit at least about 50% of the biologic activity relative to the activity of the biologic drug formulated at a manufacturing facility. More preferably, the biologic drugs exhibit at least about 80 percent of the activity, and even more preferably, at least about 95 percent of the activity after processing compared to a biologic processed at the manufacturing facility.

Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
